At a hunch I would say that is from after they stopped making glass and started buying it in - so rather recent. I've been unable to follow what they bought from whom to supply they outlets - it used to be Zwiesel but realistically it could be anything. They are no longer a producer but a dealer.

that vaguely reminds me of a cheese plate/board I had that was by Ingridglas. I will see if I can find any pics of it to compare.this was the thread.. I can't see your picture clearly to compare but it might be helpful - would it be possible please to upload your picture directly to the board as otherwise they get lost in time to come? many thankshttp://www.glassmessages.com/index.php/topic,33834.msg183059.html#msg183059m
